Abstract
Dielectric capacitors are essential for high-power, fast-response electronics, but their performance is limited by trade-offs between high polarization, low hysteresis loss, and high breakdown strength. The urgent need for eco-friendly materials has spurred intense interest in lead-free oxide dielectrics. Recent advances in synthesis and advanced characterization have revealed that atomic- and nanoscale local structures exert a profound influence on energy-storage performance. Specifically, local polar nanoregions, chemical inhomogeneities, lattice distortions, and interfacial architectures play a pivotal role in regulating polarization configuration, leakage behavior, and breakdown pathways.
